Hadco Brake Drum


Could anybody help me locate a Hadco Eng. Co. LA 10" brake drum #440? The bearing numbers are: outside bearing number: tyson M12649; inside bearing number: timken LM48548? I believe these drums were on early Airstream and Aristocrat trailers. Thank you in advance.

This axle supplier was used on Silver Streak right up until the 1980's. I emailed them once on mine, but had no response (was looking for shock absorber specifications). The PO had already converted the brakes to DEXTER units.
